Wireless communication method and wireless communication terminal using wake-up radio

An operation method of a wireless communication terminal for transmitting and receiving a signal through a first waveform, and receiving a signal through a second waveform different from the first waveform, the method comprising:

• receiving, from a base wireless communication terminal, an acceptance frame for accepting a request for wake-up radio (WUR) mode entry in which the wireless communication terminal operates based on a signal transmitted through the second waveform;
• stopping an operation of the wireless communication terminal related to a service period based on the acceptance frame, wherein the service period is a target wake time (TWT) service period which is a time period that arrives in a period negotiated between the base wireless communication terminal and the wireless communication terminal before the wireless communication terminal enters the WUR mode, and a time period which is configured for the wireless communication terminal to transmit data to and receive data from the base wireless communication terminal through the first waveform in a power save (PS) mode;
• after stopping the operation of the wireless communication terminal related to the service period, when receiving, from the base wireless communication terminal, a wake-up frame that triggers a wake-up of a wireless transceiver of the wireless communication terminal, waking-up the wireless transceiver based on the wake-up frame;
• and
• maintaining a state in which transmission and reception are possible through the wireless transceiver during at least a first service period that arrives after receiving the wake-up frame, wherein the wireless transceiver is a transceiver that receives a signal through the first waveform, the acceptance frame is received through the first waveform, and the wake-up frame is received through the second waveform,
• wherein the first service period is a period in which buffered data is transmitted from the base wireless communication terminal to the wireless communication terminal and a service period that arrives first after a primary connectivity radio (PCR)transition delay elapses from the time point at which the wake-up frame is received, and
• wherein the PCR transition delay represents a time taken from a state in which a frame cannot be transmitted and received through the first wireless transceiver to a state in which transmission and reception are possible.
